FIELD OF THE INVENTION

Certain embodiments of the invention relate to electronic paymenttransaction systems. More specifically, certain embodiments of theinvention relate to a method and system for communicating location of amobile device for hands-free payment.

BACKGROUND OF THE INVENTION

Web-based deal advertising companies offer deals to consumers withincentives to use centralized server-based social networking sites. Oneof the limitations of these approaches is that the deals are offered bystores and advertised by deal advertising companies, or the storesthemselves, without knowledge of the location of their subscribedmembers and other shoppers. The location of a person, however, may beimportant in brick and mortar shopping, since people are more likely tobuy from stores that are in their close proximity. Another limitation ofcurrent deal advertising approaches is that they use traditional socialnetworking where the deal is recommended or forwarded to one's friends.However, most of those friends may not be physically near therecommended stores. On the other hand, if a person is near a deal storethen there may be many other shoppers nearby that are not his/her friendbut who may be looking for similar deals and coupons.

The proliferation of mobile devices such as smart phones, netbooks andtablet computers has led to a growing need to obtain accurate locationinformation of such devices. Wireless positioning may involve obtainingwireless signals and processing the signals into a location estimate.The typical information used for positioning, such as Global PositioningSystem (GPS) signals, may be processed to find the position of awireless device. For example, triangulation may be used where multiplerange or angle measurements from known positions are used to calculatethe position of a device.

The location-aware systems may differ in terms of accuracy, coverage,cost of installation, and maintenance of the systems. The GPS systemsmay use satellite signals and work in outdoor environments. However,they require direct line of sight and do not work well in an indoorenvironment. Cell tower triangulation is another method that usessignals from cellular towers to locate a wireless user. This method mayalso be limited in accuracy and reliability because of the coarse numberof cell towers from a particular service provider that a mobile user cancommunicate with, as well as multipath issues.

Further limitations and disadvantages of conventional and traditionalapproaches will become apparent to one of skill in the art, throughcomparison of such systems with some aspects of the present invention asset forth in the remainder of the present application with reference tothe drawings.

In operation, a plurality of users of mobile devices 108 ₁ . . . 108 ₇may be moving around the shopping mall 102. Although FIG. 1 illustratespedestrians in a mall, other situations, such as, the users with mobiledevices in moving vehicles, may be used without departing from thespirit and scope of the invention. Each of the plurality of mobiledevices 108 ₁ . . . 108 ₇ may be location-aware based on globalpositioning system (GPS) receivers communicating with one or moresatellites 101 ₁ . . . 101 ₄. The plurality of mobile devices 108 ₁ . .. 108 ₇ may comprise one or more wireless transceivers that may beoperable to communicate with the plurality of cellular towers 112 ₁ and112 ₂ and one or more of the plurality of access points 110 ₁ and 110 ₂.Although two cellular towers are shown in FIG. 1, smaller cellular basedbase stations, such as femtocells and picocells may be used to improvecellular coverage in indoor areas without limiting the scope of theinvention.

Other networks that could be present are Bluetooth, Radio FrequencyIdentification (RFID), WiMax, UWB, Wi-Fi Direct, and/or 60 GHz wirelessprotocols. Each type of network may have one or more implementations.For example, the WLAN 802.11 standard (also referred to as Wi-Fi) mayinclude 802.11b, 802.11a, 802.11g, 802.11z, 802.11n and Wi-Fi Direct.The cellular network may include Code Division Multiple Access (CDMA),CDMA2000, Wideband CDMA (WCDMA), Time Division Multiple Access (TDMA),Frequency Division Multiple Access (FDMA), and other multiple accesstechniques. The users inside the mall 102 may be able to use theirmobile devices 108 ₁ . . . 108 ₇ and Wi-Fi access points in hot spotareas to connect to the Internet. The users with data plans may also usethe cellular network to connect to the Internet. A deal advertisingcompany may use its deal server and a network, such as the Internet oran Intranet, to communicate with the computing servers of the stores andthe computing devices of its registered members. The deal server may usea location server to estimate the location and velocity of all itsmembers. The deal server may then dynamically generate nearby storediscount deals that match subgroups of the members or use existingnearby store deals, and forward relevant deal advertisements to themobile devices 108 ₁ . . . 108 ₇ of the members.

The mobile device 208 may determine whether it is within a generatedgeo-fence 222 of the POS device 202 based on its determined locationcoordinates. In instances where the mobile device 208 is within agenerated geo-fence 222 of the POS device 202, a notification may betriggered on the mobile device 208 indicating its presence within thegenerated geo-fence 222 of the POS device 202. The mobile device 208 maydetermine whether the POS device 202 is within its range 208 _(R) ofcommunication. Since the POS device 202 is not within its range 208 _(R)of communication, the mobile device 208 may determine whether anotherintermediate mobile device 206 or access point in the peer-to-peerad-hoc network is within its range 208 _(R) of communication. Ininstances where another intermediate mobile device 206 in thepeer-to-peer ad-hoc network 200 is within its range 208 _(R) ofcommunication, the mobile device 208 may communicate its locationcoordinates and/or payment transaction information to the intermediatemobile device 206. For example, the mobile device 208 may communicate anauthorization to execute a payment transaction when the mobile device208 is within a generated geo-fence 222 of the POS device 202 and theintermediate mobile device 206 is within a range 208 _(R) ofcommunication of the mobile device 208.

The intermediate mobile device 206 may determine whether the POS device202 is within its range 206 _(R) of communication. Since the POS device202 is not within its range 206 _(R) of communication, the intermediatemobile device 206 may communicate the location coordinates of the mobiledevice 208 and/or received payment transaction information to anotherintermediate mobile device 204 via the peer-to-peer ad-hoc network 200.For example, the intermediate mobile device 206 may communicate anauthorization to execute a payment transaction to the intermediatemobile device 204 when the mobile device 208 is within a generatedgeo-fence 222 of the POS device 202 and the intermediate mobile device204 is within a range 206 _(R) of communication of the intermediatemobile device 206.

The intermediate mobile device 204 may determine whether the POS device202 is within its range 204 _(R) of communication. Since the POS device202 is within its range 204 _(R) of communication, the intermediatemobile device 204 may communicate the mobile device's 208 locationcoordinates and/or payment transaction information to the POS device 202via the peer-to-peer ad-hoc network 200. For example, the intermediatemobile device 204 may communicate an authorization to execute a paymenttransaction to the POS device 202 when the mobile device 208 is within agenerated geo-fence 222 of the POS device 202 and the POS device 202 iswithin a range 204 _(R) of communication of the intermediate mobiledevice 204.

The user with the mobile device 208 may choose to purchase one or moreitems within the store or the generated geo-fence 222. When the userwith the mobile device 208 is ready to checkout, the mobile device 208may communicate an authorization via the peer-to-peer ad-hoc network 200to the POS device 202 to execute a payment transaction based on the oneor more items chosen to be purchased when the mobile device 208 iswithin the defined geo-fence 222.

The mobile device 208 may receive an authorization response for theexecuted payment transaction from the POS device 202 via thepeer-to-peer ad-hoc network 200. For example, if the mobile device 208is within a range of communication of the POS device 202, the mobiledevice 208 may receive an authorization response for the executedpayment transaction directly from the POS device 202. In instances wherethe mobile device 208 is not within a range of communication of theselected POS device 202, the mobile device 208 may receive anauthorization response for the executed payment transaction from the POSdevice 202 via one or more intermediate mobile devices 204 and 206and/or access points 218 with a range 218R of communication in thepeer-to-peer ad-hoc network 200. In accordance with an embodiment of theinvention, the user with the mobile device 208 may be able to executethe payment transaction without physically using or swiping a credit ordebit card, or without physically tapping or holding the mobile device208 near the POS device 202.

In accordance with another embodiment of the invention, a POS device 202may communicate discounted deal information and referral rewardinformation to the mobile device 204. The mobile device 204 maycommunicate discounted deal information and referral reward informationto the access point 218 and the mobile device 206. The access point 218may then communicate the discounted deal information and referral rewardinformation to mobile devices 206 and 212 within its range 218 ₈ ofcommunication. The mobile device 206 may then communicate the discounteddeal information and referral reward information to mobile devices 208and 207 within its range 206 _(R) of communication. In one embodiment ofthe invention, the intermediate mobile devices may act as networkingrouters and may forward the personal referral link and message of thePOS device 202 to destination users of mobile devices 207 and 208. Inthe event that a destination user with mobile device 207 or 208purchases the deal, the POS device 202 may allocate a reward to theoriginal referral source mobile device 204. Multiple sources can eachhave their personalized referral links and forward the same deal to onedestination. If a destination user receives multiple referrals for thesame deal, the user can then decide which referral link to use.

In another embodiment of the invention, each intermediate user of mobiledevices 204 and 206 may access a deal advertising server in the POSdevice 202, set up an account if not already registered, receive apersonalized referral link and message, and forward to the next user. Ifthe destination user of mobile device 207 and/or 208 purchases the deal,then the POS device 202 may allocate a reward to the last referralsource mobile device 206.

In another embodiment of the invention, a portion of the intermediateusers with mobile devices 204 and 206 may register with the dealadvertising server in the POS device 202 and receive their personalizedreferral links and messages, while other mobile devices may forward thepersonalized links and messages they receive. If the destination user ofmobile device 207 and/or 208 purchases the deal, then the POS device 202may allocate a portion of the reward to the last referral source mobiledevice 206 and allocate a portion of the reward to the original referralsource mobile device 204. The intermediate users of mobile devices 204and 206 that act as routers and forward the personalized referral linksand messages of other users are using the resources of their mobiledevices, such as battery energy and CPU. These users may not want toreceive their own personalized referral links but might demand to berewarded in some way if they are to allow others to use their mobiledevices as routers in an ad-hoc network. In accordance with anotherembodiment of the invention, the original referrer or user of mobiledevice 204 may specify a separate shared reward amount for intermediaterouters.

In accordance with another embodiment, when a user of a mobile device,for example, mobile device 206, may enter or leave a geo-fence 222, oneor more software downloads and upgrades may be downloaded on to themobile device 206. For example, when mobile device 206 enters thegeo-fence 222 of a mall an interactive map of the mall with dealadvertisements may be downloaded on to the mobile device 206. In anotherembodiment, when a user of a mobile device 206 may enter or leave ageo-fence 222, the sound of the mobile device 206 may be turned on orswitched off, or a volume of the mobile device 206 may be turned higheror lower. For example, when the mobile device 206 enters the geo-fence222 of a library or a movie theater, the sound of the mobile device 206may be turned off. In another embodiment, when a user of a mobile device206 may enter or leave a geo-fence 222, the mobile device 206 may bepowered down or enter a sleep mode or powered up or activated, forexample. In another embodiment, calendar reminders may be linked to thelocation of a geo-fence 222, location-based reminders may be created, areminder may be sent with an email, SMS, vibration, voice, or facsimile(FAX) when a mobile device 206 enters or leaves the geo-fence 222. Forexample, when the user enters a shopping mall, a shopping list remindermay be sent to the mobile device 206. In another embodiment, the actionsof a user with the mobile device 206 may be monitored and data-minedwhen they enter or leave a geo-fence 222. For example, when a userenters a geo-fence 222 that marks the boundary of a store, a software orweb service may monitor the actions of that user in terms of the amountof time they spend at certain store areas and which products they showthe most interest in. This information may then be used to present themwith personalized deal advertisements on their mobile device 206, onelectronic billboards and displays near them, or send them conventionalmail marketing material.

In another embodiment, when a user of a mobile device 206 may enter orleave a geo-fence 222, an email, SMS, vibration, voice, and/or FAX alertmay be communicated to the mobile device 206 or to another device suchas the mobile device 210. In another embodiment, when a user of a mobiledevice 206 may enter or leave a geo-fence 222, the user interface andfunctionality of a location-based application or a game may be changedso that it has a different look and feel with corresponding menus. Forexample, a location-based R-rated game on the mobile device 206 mayswitch to the functionality of a less violent home edition when themobile device 206 enters the geo-fence 222 of the mobile device 206user's home, and may switch back to the full version once the mobiledevice 206 leaves the geo-fence 222. In another embodiment, alocation-based application may be disabled or enabled when a user of themobile device 206 enters or leaves the geo-fence 222. For example, a kidmay not be able to play games on the mobile device 106 when the mobiledevice 206 is within a defined geo-fence, such as, a school, a library,and/or a home. In another embodiment, the Internet connectivity of themobile device 206 may be location-based and may be dynamically modifiedwhen inside a geo-fence 222, for example, using Wi-Fi for Internetconnectivity within a home or an office, and using a cellular data planfor Internet connectivity outside the geo-fence 222. In anotherembodiment, the network security settings of a mobile device 206 may bedynamically modified based on the location of the mobile device 206within or outside the geo-fence 222. For example, for an office or homewireless network, only users inside a geo-fence 222 may be allowed toconnect to the network and outside users may be denied access.

In another embodiment, a software application on the mobile device 206may be location-based and may start running and perform certainfunctions when the mobile device 206 enters or leaves the geo-fence 222.For example, when a user enters a geo-fence 222 around his/her home,his/her mobile device 206 may send an alert to software applicationsthat run on the mobile device 206 or on a different networked computer.The software applications may then turn on the lights of the house, openthe garage door or the front door, turn on the TV, turn on air coolingand/or heating, for example. Similarly, when a user leaves the geo-fence222 around his/her home, the software applications may receive an alertand turn off the lights, close all the doors, turn off the TV and otherappliances, and turn off air cooling and/or heating. In anotherembodiment, there may be several geo-fence boundaries such as 222 andwhen the mobile device 206 enters or leaves each boundary, differentactions may be triggered. For example, a large geo-fence may extendoutside the house for opening and/or closing the garage door and frontdoor, while a smaller geo-fence inside the house's living room may beused for turning the living room lights on/off.

In another embodiment, a first list of phone numbers may be created, andone or more phone numbers listed in the first list may be blocked asincoming voice calls, if the mobile device 206 is within the geo-fence222. In another embodiment, a second list of phone numbers may becreated, and one or more phone numbers listed in the second list may beblocked as incoming voice calls, if the mobile device 206 is outside thegeo-fence 222. In another embodiment, a third list of Internet webaddresses may be created, and one or more web addresses listed in thethird list may be blocked from being accessed, if the mobile device 206is within the geo-fence 222. In another embodiment, a fourth list ofInternet web addresses may be created, and one or more web addresseslisted in the fourth list may be blocked from being accessed, if themobile device 206 is outside the geo-fence 222.

In another embodiment, a user with the mobile device 206 mayautomatically check-in at a social networking web site, for example,Foursquare or Gowalla and receive award points when the user enters thegeo-fence 222 of a particular location. This removes the need for theuser to manually check-in to get award points. In another embodiment, auser with a mobile device 206 has to enter the geo-fence 222 associatedwith a business, for example, a restaurant, a hotel, a bar, or a nightclub in order to be able to write a review on a rating web site, forexample, Yelp or Tripadvisor. The review may be written while the useris inside the geo-fence 222 or at a later time when the user is outsidethe geo-fence 222.

In another embodiment, users of a ratings web site may filter the ratingreviews of a business based on a function of the interaction of thereviewer with the geo-fence 222 associated with the business. Thefunction may vary depending upon factors, such as, has the reviewer everbeen inside the geo-fence 222, how many times has the reviewer beeninside the geo-fence 222, what times and dates have the reviewer beeninside the geo-fence 222. The users of the ratings web site may, forexample, filter out or assign a smaller weight to reviews from peoplewho have not been inside the geo-fence 222 of a particular business, buthave nonetheless written a review. This allows users of the rating website to ignore or assign a smaller weight to the reviews from people whohave written biased reviews of businesses such as hotels, brick andmortar stores, restaurants, and night clubs without visiting them.Similarly, users of the rating web site may filter out or assign asmaller weight to reviews from people who have spent excessive timeinside the geo-fence 222 of a business. This may allow users of therating web site to filter out or assign a smaller weight to the reviewsfrom people who work for a business and write biased reviews on thatbusiness. In another embodiment, users of a ratings web site may filterthe rating reviews of a business based on a function of the interactionof the reviewer with the geo-fence 222 associated with the business aswell as the geo-fence 222 of related businesses. The geo-fence 222 maynot only describe the geography it encloses, but may also have otherproperties, such as, a business category, for example, a restaurant, ahotel, a bar or a night club. For example, a person who has been insidethe geo-fence 222 of many restaurants over a period of time as well asthe geo-fence 222 of restaurant X can be considered an experiencedreviewer of restaurants and his/her review of restaurant X may be givena higher weighting. In another embodiment, people posting reviews on arating web site have stored their information with the web site. Theinformation may include home address, age, marital status. Users of theratings web site can then filter the reviews of others based on complexqueries such as interaction of the reviewer with one or more geo-fences112, their home and/or work address, their demographics, and theircurrent tracked location. For example, users of the rating web site canquery the web site to “Show the top five highest rated hotels in Cancunfrom people who have been inside the geo-fences of the hotels in thepast”, or “Show the top five highest rated hotels in Cancun from peoplewho have been inside the geo-fences of the hotels in the past and havebeen inside the geo-fences of at least 10 other hotels in Cancun in thepast”, or “Show the top five highest rated hotels in Cancun from peoplewho live in California and who have been inside the geo-fences of thehotels in the past”, or “Show the top five highest rated hotels inCancun from people with kids who live in California and who have beeninside the geo-fences of the hotels in the past”, or “Show the top fivehighest rated hotels in Cancun from people with kids whose presenttracked location is California and who have been inside the geo-fencesof the hotels in the past”. These query methods can be supplied to userswith a simple user interface that has for example multiple checkboxesand fields that allow combining simple queries into more complexqueries. It is possible for a person posting a review on the ratings website to login and post their review with a different computing devicethan their mobile position tracking device. People posting reviews ofbusinesses on the ratings web site may disable position tracking or notprovide it. However, as a result, their reviews may be assigned lessweight by the ratings web site or by users of the ratings web site sincethere is no record of the reviewers being in the geographical proximityof the places they are reviewing.

In another embodiment, a user with the mobile device 206 who enters ageo-fence 222 may receive notifications to inform him/her which ofhis/her friends are inside the geo-fence 222 area. The notification maybe via an email, SMS, vibration, voice, map on the display of the mobiledevice 206, and/or a FAX alert. Similarly, when a user with the mobiledevice 206 leaves a geo-fence area 222 he/she may automatically checkout and/or send notifications to his/her friends to notify them thathe/she is no longer inside the geo-fence 222. In another embodiment, amoving object may be carrying a first position tracking device withinthe mobile device 206 and when the mobile device 206 enters or leaves ageo-fence 222, a notification may be sent to a second mobile device 210.The notification may be via an email, a SMS, vibration, voice, FAXalert, and/or map on the display of the mobile device 210 with thepositions of the mobile device 206, the geo-fence 222, and the mobiledevice 210. For example, the mobile device 206 may be attached to achild that is being tracked by a parent with the mobile device 210, orthe mobile device 206 may be attached to a company vehicle that is beingtracked by a supervisor, or the mobile device 206 may be attached to alivestock that is being tracked by a farmer.

FIG. 3A is a diagram of an exemplary display showing a schematic mapindicating defined geo-fences and a location of one or more mobiledevices within the defined geo-fences, in accordance with an embodimentof the invention. Referring to FIG. 3A, there is shown a display 300.The display 300 may be a display of the POS device 202 or may be adisplay of one of the mobile devices 208, for example.

The display 300 may indicate a map 302 of a store, a shopping mall, or arestaurant, for example. The map 302 may indicate a peer-to-peer ad-hocnetwork 301 comprising a plurality of POS devices 304, 306, and 308, andone or more corresponding defined geo-fences 303, 305 and 307 around thePOS devices 304, 306, and 308 respectively, which may representindividual stores in a shopping mall or restaurants in a food court, forexample. The display 300 may indicate a location of one or more accesspoints 310 ₁ . . . 310 ₅, and one or more mobile devices 312 ₁ . . . 312₉. The display 300 may also indicate a speed of movement and a directionof movement of the plurality of mobile devices 312 ₁ . . . 312 ₉ at theselected plurality of POS devices 304, 306, and 308. Accordingly, staffmay be assigned to designated sections of a store or stores in a mallbased on the indicated speed of movement and the direction of movementof the plurality of mobile devices 312 ₁ . . . 312 ₉ at the selectedplurality of POS devices 304, 306, and 308. The staff at the POS devices304, 306, and 308 may also correlate the speed and/or direction andidentifying information of users of mobile devices 312 ₁ . . . 312 ₉ onthe map 302 with their own visual sight of the people in their vicinityand use that information when they interact with the users of the mobiledevices. The store advertising displays may also use the speed anddirection information, where displays that are facing a user with amobile device and are about to come into his/her range of view areactivated and present customized information and advertisement to theuser.

A POS device, for example, POS device 304 may determine whether aselected mobile device 312 ₆, for example, is within a generatedgeo-fence 303 of the POS device 304. In instances where the selectedmobile device 312 ₆ is within a generated geo-fence 303 of the POSdevice 304, a notification may be triggered on the display 300 of thePOS device 304 indicating the presence of the selected mobile device 312₆ within the generated geo-fence 303 of the POS device 304. The POSdevice 304 may determine whether the selected mobile device 312 ₆ iswithin its range of communication. In instances where the selectedmobile device 312 ₆ is within a range of communication of the POS device304, the POS device 304 may communicate advertisement, discounted dealand/or payment transaction information to the selected mobile device 312₆ directly or via the peer-to-peer ad-hoc network 301. The POS device304 may be operable to store the user's past purchases with the store orrestaurant, credit and/or debit card authorizations associated with theuser, returns, exchanges, layaways, gift cards, gift registries, and/orcustomer loyalty programs associated with the user. For example, the POSdevice 304 may communicate advertisement information and/or discounteddeal information for one or more items recently purchased by the user ofthe mobile device 312 ₆ when the selected mobile device 312 ₆ is withina generated geo-fence 303 of the POS device 304 and the selected mobiledevice 312 ₆ is within a range of communication of the POS device 304.

In instances where the selected mobile device 312 ₆ is not within arange of communication of the POS device 304, the POS device 304 maydetermine whether another intermediate mobile device 312 ₄ in thepeer-to-peer ad-hoc network 301 is within its range of communication.The POS device 304 may communicate advertisement, discounted deal,referral reward, and/or payment transaction information to theintermediate mobile device 312 ₄ in the peer-to-peer ad-hoc network 301.For example, the POS device 304 may communicate advertisementinformation and discounted deal information for one or more itemsrecently purchased by the user of the mobile device 312 ₆ to theintermediate mobile device 312 ₄ when the mobile device 312 ₆ is withina generated geo-fence 303 of the POS device 304 and the intermediatemobile device 312 ₄ is within a range of communication of the POS device304. The POS device 304 may also communicate referral reward informationto the intermediate mobile device 312 ₄.

The intermediate mobile device 312 ₄ may determine whether the selectedmobile device 312 ₆ is within its range of communication. In instanceswhere the selected mobile device 312 ₆ is not within a range ofcommunication of the intermediate mobile device 312 ₄, the intermediatemobile device 312 ₄ may communicate advertisement, discounted deal,referral reward, and/or payment transaction information to anotherintermediate mobile device 312 ₅ via the peer-to-peer ad-hoc network301. For example, the intermediate mobile device 312 ₄ may communicateadvertisement information and discounted deal information for one ormore items recently purchased by the user of the mobile device 312 ₆ tothe intermediate mobile device 312 ₅ when the selected mobile device 312₆ is within a generated geo-fence 303 of the POS device 304 and theintermediate mobile device 312 ₅ is within a range of communication ofthe intermediate mobile device 312 ₄. The intermediate mobile device 312₄ may also communicate referral reward information to the intermediatemobile device 312 ₅.

In instances where the mobile device 312 ₆ is within a range ofcommunication of the intermediate mobile device 312 ₅, the intermediatemobile device 312 ₅ may communicate advertisement, discounted dealand/or payment transaction information to the selected mobile device 312₆ via the peer-to-peer ad-hoc network 301. For example, the intermediatemobile device 312 ₅ may communicate advertisement information anddiscounted deal information for one or more items recently purchased bythe user of the mobile device 312 ₆ to the selected mobile device 312 ₆,when the selected mobile device 312 ₆ is within a generated geo-fence303 of the POS device 304 and the selected mobile device 312 ₆ is withina range of communication of the intermediate mobile device 312 ₅.

The user with the mobile device 312 ₆ may choose to purchase one or moreitems within the store or the generated geo-fence 222. When the userwith the mobile device 312 ₆ is ready to checkout, the mobile device 312₆ may communicate an authorization via the peer-to-peer ad-hoc network301 to the POS device 304 to execute a payment transaction based on theone or more items chosen to be purchased when the mobile device 312 ₆ iswithin the defined geo-fence 303. The POS device 304 may authenticatethe received payment transaction information from the mobile device 312₆. For example, the POS device 304 may authenticate the received paymenttransaction information from the selected mobile device 312 ₆ based onone or more of a voice recognition, a gesture, a computer facerecognition and/or a biometric recognition, for example.

In accordance with another embodiment, the POS device 304 may comprise avideo camera to record the transaction. A user of the mobile device 312₆ may give the authorization, for example, the user may say “Put it onmy account” which may be video recorded by the POS device 304 and storedin a database to later resolve any potential disputes of a transaction.In another embodiment, the POS device 304 may comprise a biometricsinput device to record the transaction. A user of the mobile device 312₆ may give the authorization, for example, via a biometric scan, whichmay be stored in a database to later resolve any potential disputes of atransaction.

The POS device 304 may communicate an authorization response oracknowledgement for the executed payment transaction to the mobiledevice 312 ₆ via the peer-to-peer ad-hoc network 301. For example, ifthe selected mobile device 312 ₁ is within a range of communication ofthe POS device 308, the POS device 308 may communicate an authorizationresponse for the executed payment transaction directly to the selectedmobile device 312 ₁. In instances where the selected mobile device 312 ₁is not within a range of communication of the POS device 308, the POSdevice 308 may communicate an authorization response for the executedpayment transaction to the selected mobile device 312 ₁ via one or moreintermediate mobile devices 312 ₂ and/or access points 310 ₁ in thepeer-to-peer ad-hoc network 301.

In accordance with another embodiment of the invention, a POS device 308may be operable to determine the location coordinates of a mobile device312 ₁ within a 10 meter radius, for example. Accordingly, the POS device308 may authenticate the received payment transaction information fromthe mobile device 312 ₁ only when the mobile device 312 ₁ is within aparticular defined geo-fence 307. In other words, the POS device 308 maynot authenticate the received payment transaction information from themobile device 312 ₁ when the mobile device 312 ₁ is outside the definedgeo-fence 307 or within a neighboring store or defined geo-fence 303,for example. In another embodiment of the invention, the mobile device312 ₁ may preset its settings to selectively trigger an authorization toexecute the payment transaction when the mobile device 312 ₁ is within adefined geo-fence 307, and may choose not to trigger an authorizationresponse to execute the payment transaction when the mobile device 312 ₁is outside the defined geo-fence 307 or within a neighboring store ordefined geo-fence 303.

In another embodiment of the invention, the mobile device 312 ₁ may alsochoose to purchase one or more items from a neighboring store or definedgeo-fence 305. Accordingly, the POS device 306 in the neighboringgeo-fence 305 may be operable to store the user's past purchases withthe store, credit and/or debit card authorizations associated with theuser, returns, exchanges, layaways, gift cards, gift registries, and/orcustomer loyalty programs associated with the user. The mobile device312 ₁ may preset its settings to selectively trigger an authorization toexecute the payment transaction when the mobile device 312 ₁ is withinthe defined geo-fence 305

In accordance with another embodiment of the invention, a POS device 308may notify one or more members in the shopping mall 102 about a deal 1advertisement from store A with a defined geo-fence 307. The POS device308 may also use one or more of the access points 310 ₁ . . . 310 ₅ tobroadcast the deal to nearby mobile devices that are within itstransmission range. This deal may be dynamically generated by contactingstore A, or it could be a pre-existing store A deal. In both cases thePOS device 308 may use the users' locations and profiles in determininga match between the deal and the members. Different members may receiveadvertisements about different deals based on their location, purchasehistory, referral history, wish-lists and other profiles. In thisexample, mobile devices 312 ₁ and 312 ₂ may receive an advertisementabout the deal from store A because they are potential buyers of theadvertisement and/or because they are potential referrers to othershoppers. The users with mobile devices 312 ₁ and 312 ₂ may then havethe option to purchase the deal, and/or use ad-hoc social networking toadvertise the deal to near-by shoppers with mobile devices 312 ₃ . . .312 ₉. For example, mobile device 312 ₇ may not receive theadvertisement from the POS device 308 because its user's profile orlocation (too distant from store A) may not match the advertisement.Some registered members may also not receive advertisements because theydo not have network connectivity or because they have disabled positiontracking and the POS device 308 may not know their location. In somecases, other users may also receive advertisements either directly fromthe POS device 308 or through member referrals with standard networkinginfrastructure and communication servers (email, chat, text message, ashopping portal web site, conventional server-based social networking).

In accordance with an embodiment of the invention, if there are multipledeals from one or more stores a member may receive one advertisement forall the deals that includes a graphical dynamic map 302 with thelocation of all nearby deals, or separate advertisements for each deal.The users of the mobile devices may be using a software program to viewdiscount deals as they move around the shopping mall 102. This softwaremay be code running on a browser, or it could be a mobile deviceapplication that is running a session with a deal advertising server inthe POS device 304. The user may be authenticated with the POS device304 and may view personalized deal advertisements. A map server in thePOS device 304 may use the position and velocity information of the userand its map database to generate a dynamic map 302. The user's positionmay be illustrated on the map 302 with different methods, such as colorcoding or a circle with a radius that increases with positionuncertainty. The map 302 may display the member's name, position, traveldirection, and provide directions to the deal of interest. The speed ofthe user may be conveyed with different methods such as the length of adirection arrow or numerical overlays on the map 302. The map 302 mayalso display nearby stores and nearby deals. In one embodiment of theinvention, deal 1 which is the nearest deal at store A may be featured.The featured deal may have a description of the deal that states thecost to the user and the savings of the deal compared to a regularprice. The deal conditions may also be noted such as the duration of thedeal, number of items available, required minimum number of itemsrequested by buyers to activate the deal, and the discount function. Amember may filter the deals or select a particular one and receivedirections to the store and also directions inside the store to get tothe deal item.

In a deal-server centric approach, a buyer can select the quantity ofthe desired item, if applicable, and express interest in purchasing thedeal. The deal advertising server in the POS device 304 may check todetermine whether the deal conditions are met. Deal conditions mayinclude, for example, if a minimum required number of buyers haveexpressed interest, if the item is still available, and if the potentialbuyer qualifies for the deal (e.g. minimum age requirement). If the dealconditions are met then the transaction server in the POS device 304 maycharge the buyer and credit the store in exchange for a transaction fee(if multiple stores are involved it credits different amounts to eachstore). The POS device 304 may communicate an electronic receipt to themobile device 312 ₆ of the buyer. The buyer may then visit the store,show the electronic receipt, and receive the item. The buyer may alsorequest shipment of the item to a shipping address and not even visitthe store.

In an exemplary embodiment of the invention, if a user with mobiledevice 312 ₂ buys a gift card from the POS device 308, the user canvisit the store to pick store items and use the electronic receipt. Oncethe user is at the store, the user can use the mobile device 312 ₂ toscan and price items. For example, the mobile device 312 ₂ can use itscamera or a scanner to scan the barcodes of items. Alternatively, if theitems have RF tags with price information, the user can use her mobiledevice 312 ₂ with an RF tag reader to scan the prices. After the userhas picked the store items, the user can use the Near FieldCommunication (NFC) component of her mobile device 312 ₂, which acts asa smart card, to communicate with a store reader and exchange the giftcard receipt for the items. If the items cost more than the gift cardshe can pay the additional amount with a mobile device NFC card paymentmethod, for example.

In accordance with another embodiment of the invention, a POS device 304may be operable to define multiple geo-fences and each geo-fence maycover different areas for different applications. For example, thegeo-fence for a location-based hands-free payment may be inside thestore or geo-fence 303 and a small distance or radius from the POSdevice 304, while the geo-fence for sending deal advertisements maycover a larger distance and even include locations outside the store,for example, the stores and areas disclosed in map 302. Notwithstanding,a store may have multiple POS devices. A deal advertisement may be sentfrom the store's server rather than a particular POS device within thestore, for example.

In accordance with another embodiment of the invention, the users ofmobile devices may use their mobile device 312 ₆ to browse products ofnearby merchants, make a reservation and/or place an order, and thenwhen they are near a merchant's POS device 304, may complete thetransaction. The geo-fence for placing an order may be different, forexample, the stores and areas disclosed in map 302, compared to thegeo-fence 303 for proximity to the POS device 304 and completion of thetransaction.

FIG. 3B is a diagram of another exemplary display indicating a locationof one or more registered mobile devices on a schematic map, inaccordance with an embodiment of the invention. Referring to FIG. 3B,there is shown a display 350. The display 350 may be a display of thePOS device 352.

The display 350 may indicate a POS device 352 and its associatedgeo-fence 354 of a store, a shopping mall, or a restaurant, for example.The display 350 may indicate a location of one or more mobile devices356 ₁ . . . 356 ₄ within the defined geo-fence 354. The display 350 mayindicate a plurality of registered users with corresponding mobiledevices within the geo-fence 354 in a column on one side of the display.For example, the display 350 may indicate the name, photograph, or otheridentification of users with mobile devices 356 ₁ . . . 356 ₄ as tabs358 ₁ . . . 358 ₄ respectively. The tabs 358 ₁ . . . 358 ₄ may beordered according to a distance of the registered users to the POSdevice 352. The ordering of the tabs 358 ₁ . . . 358 ₄ may be updated asthe registered users move closer or further away from the POS device352.

The users of the mobile devices 356 ₁ . . . 356 ₄ may be registeredeither with a third party server or with the POS device 200 of a store.The registration of a user may include providing user identificationcredential information, and payment information, such as credit cardinformation, or other forms of payment information, for example. Once auser is inside the geo-fence 354, the information that is transmittedfrom the mobile device 356 ₁ to the POS device 352 to complete atransaction may not include their payment method details.

The operator of the POS device 352 may be able to zoom in and out of thegeo-fence 354 and may select one or more users by clicking that user onthe display 350 or clicking a mouse with its pointer on that user in thedisplay 350, for example. When the POS device 352 selects a user on thedisplay 350, the user's details in the column display may also behighlighted. In an alternative embodiment, when the POS device 352selects a user by clicking on one of the tabs 358 ₁ . . . 358 ₄, theselected user's location on the display 350 within the geo-fence 354 maybe highlighted.

FIG. 4 is a block diagram of an exemplary POS device, in accordance withan embodiment of the invention. Referring to FIG. 4, there is shown aPOS device 400. The POS device 400 may comprise a location module 402, aprocessor 410, a memory 408, a plurality of networked servers 412, aplurality of networked databases 414, mapping data 416, and a display418.

The location module 402 may be operable to determine the locationcoordinates of the POS device 400 and/or one or more mobile devices, forexample, mobile device 208. The location coordinates may be determinedin Cartesian coordinates, latitude and longitude coordinates andaltitude for a 3D position, and polar coordinates. The location module402 may comprise a position processor 404 and a mapping processor 406.

Notwithstanding, the invention may not be so limited, and the signalingand position calculations of the mobile devices 204-216 may becontrolled by a remote networked server, for example. The plurality ofthe mobile devices 204-216 may be operable to communicate theirdetermined location coordinates to a remote networked server, forexample, a server at the social networking site Foursquare.

FIG. 5 is a block diagram of an exemplary mobile device, in accordancewith an embodiment of the invention. Referring to FIG. 5, there is showna mobile device 502.

The mobile device 502 may comprise a plurality of radios and antennas504 ₁ . . . 504 ₄ to receive and transmit signals associated with theone or more radios. For example, the mobile device 502 may comprise aGPS radio 506, a UWB radio 508, a WiMax radio 510, a WLAN radio 512, aBluetooth radio 514, a NFC radio 516, a cellular radio 518, a RFIDreader 520, and a 60 GHz radio 522. Notwithstanding, the invention maynot be so limited and other radios capable of transmitting and receivingsignals using one or more other protocols may be utilized withoutlimiting the scope of the invention. Furthermore, the mobile device 502may comprise a subset of the listed radios in FIG. 5 without limitingthe scope of the invention.

The mobile device 502 may further comprise a clock 524, a positionmodule 526, a processor 528, a memory 530, and a navigation module 532.The mobile device 502 may be operable to be used about a geographicalarea of interest. For instance, the mobile device 502 may be within avehicle, such as, a passenger car or a commercial truck equipped withradios to receive signals and can move to locations within ageographical area of interest. In indoor environments, a mobile device502 may be carried by a user. In some embodiments of the invention, themobile device 502 may be a portable wireless device, a consumerhand-held wireless device, a GPS-enabled media player, or a GPS-enabledlaptop, for example.

The plurality of radios 506-522 in the mobile device 502 may beMultiple-Input Multiple-Output (MIMO) systems that have multipleantennas, which transmit independently and accordingly improve theaccuracy by providing more channel characteristics or parameters. TheNFC radio 516 may be operable to read barcodes, smart cards, andinterface with electronic payment systems. A GPS is a CDMA system thatuses Pseudo Noise (PN) codes with embedded data that provide satellitelocations and times. The GPS radio 506 may be of commercial quality insome embodiments and may be used to characterize the GPS communicationchannel. In some embodiments of the invention, the GPS radio 506 mayalso provide position values for all other radio communication channelreadings.

The processor 528 may comprise suitable logic, circuitry, interfaces,and/or code that may be operable to manage the operations of theplurality of radios 506-522. For example, the processor 528 may instructone of the plurality of radios 506-522 to scan for a particular signaland perform a channel measurement on a particular frequency with aparticular fast Fourier transform (FFT) size and measurement time. Theparticular radio, for example, WLAN radio 512 may process the receivedsignals to characterize the communication channel of that radio. Theprocessor 528 may then transfer the channel parameters in an appropriateformat into local memory 530. The configuration of most of the wirelessnetworks may not change with time since the signal sources, such as celltowers or permanent wireless access points do not move. However, somenetworks change with time because the signal sources move, such as, GPSsatellites make complete orbits of the earth every 24 hours. For thosechannels that exhibit a time varying dimension, the channels arecharacterized at different time instances. The clock 524 may be used totime stamp the channel parameters that are stored in the local memory530. In some embodiments of the invention, the clock 524 may be obtainedfrom a cellular tower, clocks of GPS satellites, or other externalsources.

The mobile device 502 may have a number of dedicatedapplications such as deal advertising, ad-hoc social networking, profileeditor and matcher, server-based social networking, email, instantmessenger, chat, SMS, and/or camera. The mobile device 502 may have abrowser that can browse information on the intranet/Internet anddownload other applications from the network. A bus may link all thesecomponents with the processor 528 and memory 530.

The mobile device 502 may also comprise a magnetometer sensor that mayprovide the orientation of the mobile device 502 in three dimensions totag the content with 3D orientation information, and an accelerometerthat may calculate the velocity magnitude and angle to tag the contentwith current velocity and velocity angle. The mobile device 502 maycomprise one or more applications that may use the position module 526to tag generated content with location information. The position module526 may provide latitude and longitude information or some othercoordinate system. The position module 526 may also convert thelatitude/longitude information to street addresses for maps. Thelocation coordinates, 3D orientation, velocity, and data/timeinformation may be included in the generated content, coded in thefilename of the content, or stored and sent in a separate metafile ormessage that is associated with the content. The content generated byapplications such as email, chat, SMS, social networking tools, and/or acamera may be complemented with location, orientation, velocity, anddate/time information, if the user/member chooses to do so by settingthe appropriate security preferences at the content level or at theapplication level. The mobile device 502 may upload the geo-taggedcontent for storage on networked geo-tagged user content databases. Someof the user security preferences may be stored locally on the mobiledevice 502, while others may be stored on user/member profile databasesthat are accessible to networked servers that provide applications (e.g.email, chat, social networking). If a member has disabled continuousposition tracking but has enabled content tagging, then the uploadedgeo-tagged content may be used to extract position and velocityinformation.

In accordance with an embodiment of the invention, the mobile device 502may retrieve a first set of parameters from a reference database in thePOS device 202 corresponding to a plurality of signals received at thecurrent location coordinates of the mobile device 502. The referencedatabase in the POS device 202 may store channel parameterscorresponding to the plurality of signals received at each of aplurality of location coordinates of the plurality of mobile devices inthe network. The mobile device 502 may determine its locationcoordinates based on comparing the retrieved first set of parameterswith the stored parameters in the reference database. The retrievedfirst set of parameters and the stored parameters in the referencedatabase may comprise one or more of a time of arrival (TOA) delayextracted using received signal strength indicator (RSSI) transition, atime of arrival delay extracted using signal preamble correlation, atime difference of arrival (TDOA), a transmitted signal strength, anangle of arrival (AOA), equalizer filter coefficients, channel multipathprofile, channel fast Fourier transform (FFT) coefficients, beaconsignal strength, phase of each pilot tone, amplitude of each pilot toneand/or Doppler shift associated with movement of the plurality of mobiledevices, for example, mobile device 502.
